The Value of a Coherent Calibration

When you send your meter or sensor back for service, Coherent provides much more than just a calibration.

Many of our meters and sensors service items include both calibration and minor repairs. This means that in addition to calibration we replace damaged components and recertify the product as able to perform to the same specifications as when it was new.  In addition, eligible products receive an extended 12 month warranty following recertification. This is the same 12 month warranty we offer on a brand new product.

A large percentage of our calibrations are performed within five business days, and expedited service is available, to minimize our customer’s downtime.

Calibration of a Coherent power and energy laser measurement product includes:

• Calibration to original uncertainty levels
• Minor repairs (see note below)
• Extended 12 month warranty, on eligible products
• Fast calibration turn around time.

Minor repairs includes fixing manufacturer’s defects, hardware updates, firmware, software updates, damaged connectors, and other small repairs. Detector element replacement due to laser damage and damage caused by negligent use is not covered – for customer caused damaged an additional repair service charge is applied.

This level of service results in an overall lower cost of ownership for our customers. Those customers who routinely send products in for annual calibration are realizing a lifetime warranty for their products.

By choosing Coherent you are choosing a company you can rely on for fast delivery, low warranty rate, and lower overall cost of ownership.

Recertify Once a Year 

Coherent laser power and energy meters are precision instruments, capable of delivering very accurate measurements as well as providing many years of useful service. To maintain this high level of performance, and to ensure compliance with your quality and ISO certification, it is important to have your measurement system serviced and recertified once per year.

Extended use of laser power and energy meters and sensors, as well as environmental factors, can have an adverse effect on accuracy and also result in wear and/or damage to parts critical to optimum performance.
